No one at the time would have regarded it as a controversial statement. The Nazis could hardly have been more open in their socialism, describing themselves with the same terminology as our own SWP: National Socialist German Workers' Party.

Almost everyone in those days accepted that fascism had emerged from the revolutionary Left. Its militants marched on May Day under red flags. Its leaders stood for collectivism, state control of industry, high tariffs, workers' councils. Around Europe, fascists were convinced that, as Hitler told an enthusiastic Mussolini in 1934, 'capitalism has run its course'.

One of the most stunning achievements of the modern Left is to have created a cultural climate where simply to recite these facts is jarring. History is reinterpreted, and it is taken as axiomatic that fascism must have been Right-wing, the logic seemingly being that Left-wing means compassionate and Right-wing means nasty and fascists were nasty. You expect this level of analysis from Twitter mobs; you shouldn't expect it from mainstream commentators....

Leftists become incandescent when reminded of the socialist roots of Nazism
...On 16 June 1941, as Hitler readied his forces for Operation Barbarossa, Josef Goebbels looked forward to the new order that the Nazis would impose on a conquered Russia. There would be no come-back, he wrote, for capitalists nor priests nor Tsars. Rather, in the place of debased, Jewish Bolshevism, the Wehrmacht would deliver “der echte Sozialismus”: real socialism.

Goebbels never doubted that he was a socialist. He understood Nazism to be a better and more plausible form of socialism than that propagated by Lenin. Instead of spreading itself across different nations, it would operate within the unit of the Volk...

...The idea that Nazism is a more extreme form of conservatism has insinuated its way into popular culture. You hear it, not only when spotty students yell “fascist” at Tories, but when pundits talk of revolutionary anti-capitalist parties, such as the BNP and Golden Dawn, as “far Right”.

What is it based on, this connection? Little beyond a jejune sense that Left-wing means compassionate and Right-wing means nasty and fascists are nasty. When written down like that, the notion sounds idiotic, but think of the groups around the world that the BBC, for example, calls “Right-wing”: the Taliban, who want communal ownership of goods; the Iranian revolutionaries, who abolished the monarchy, seized industries and destroyed the middle class; Vladimir Zhirinovsky, who pined for Stalinism. The “Nazis-were-far-Right” shtick is a symptom of the wider notion that “Right-wing” is a synonym for “baddie”.

One of my constituents once complained to the Beeb about a report on the repression of Mexico's indigenous peoples, in which the government was labelled Right-wing. The governing party, he pointed out, was a member of the Socialist International and, again, the give-away was in its name: Institutional Revolutionary Party. The BBC’s response was priceless. Yes, it accepted that the party was socialist, “but what our correspondent was trying to get across was that it is authoritarian”....
